T0 ALL WHOM IT MAY vCONCERNE Be it known that 1 T. L. GOBLE, of Orange,in theconn'ty of Se11uyler,'a.nrl` State of NeW'York, have invented anewlandimproved Wagon-Jack; and I do hereby decla-re that the followingis a full, clear, and exact description lthereof, which will enableothers'skilled in the art to make and use the same, referencefbeing hadto the accompanying-drawings, forming part of this specification.

The figure is a side view of my improvedvwagon-jack.

My invention has for its object to improve the construction of myimproved ,wagon-jack, patented April 30,

i 1867, and numbered 64,302, so as to make it lmore convenient andeffective in operation; and it consists in the combination andarrangement of the various parts, as hereinafter more fully described.

A is the base-bar of the jack, which rests up`on the ground, and, towhich the other par'ts of the` jack are attach-ed. To the forward endofthe base-bar A is rigidly attached a short standard or post, to theupper end of which the `forward end of the notched bar or rail C ispivoted. The rear end of the notched bar C is pivoted to the end of theeccentric-lever D, as shown in the drawing. E is a short standard orpost, which should be a little longer than the stationary standard B,and the lower end of which is pivoted to the rear end of the base-bar-A. To the upper end of the pivoted standard E'is pivoted 'theeccentric-lever D, as shown in the figure.

In using the jack, by lowering the free end of the eccent1'ic-lever D,the rear end Yof the notched bar C is raised, and, at the same time, theupper end f the pivoted standard E is moved forward, bringing thepivotingpoint of the upper endV of'the said standard E beneath or infront of the pivoting-point of the rear end of the` notched bar C, whichlocks the jack, and'holds it securely in place until releasedby againraising the free endr of the said eccentric-lever D.

I claim as new, and desire to secure by Letters Patent- The combinationof the base-bar A, stationary standard B, pivoted notched bar C, pivotedeccentricdefer D, and pivoted standard E, with each other, substantiallyin the manner herein shown and described, and for the purposes setforth.Y
